The hardcover (H) is worth three times the paperback (P) so:
The hardcover H will be worth "3P"
3P (the hardcover) + P (one paperback) = $27.00
3p + p = $27.00
4p = 27.00
p = $6.75
So, the paperback was $6.75 and the hardcover was three times that or $20.25

Let the cost of the paperback equal P
Since the hardcover cost 3 times as much, it is 3P
the two books cost $27 so P + 3P = 27
4P=27
P=27/4
the paperback cost $6.75
3P, or the hardcover, cost $20.25

We have the hardcover H and the paperback P
P + H = $27.00 -Both added are $27
H = 3P -Hardcover is 3 times the price of paperback
P + 3P = 27 -Since H=3P replace the fisrt formula for H.
4P = 27 - Add and divide to get P
P = $6.75 -P is 6.75
H = 3P -H is 3 times P
3P = 3 (6.57) -And 3 times P is 3 times 6.75
H = $20.25

3P + P = $27.00
4p = 27.00
p = 27/4
p = 6.75 for the paperback
27 - 6.75 = 20.25 for the hardcover
